Answer: it will be A And D
Step-by-step explanation:
I think he is not correct because there is negative number so it can't be greater than one
Answer:
v = -1
Step-by-step explanation:
First, you will need to solve it step-by-step:
(4v − 9)(1 + v) = 0
Next, you need to simplify both sides of the equation:
4v(2) − 5v − 9 = 0
Now, factor the left side of equation:
(4v − 9)(v + 1) = 0
The last thing you need to do is to set all of the factors to equal to zero:
4v − 9 = 0 or v + 1 = 0
So, that means that you answer:
v=9/4 or in your case, v = −1
Oh maybe that since the derivative of sine is cosine and cosine is bounded above by 1, then
<span><span><span><span>sin(x)−sin(0) /</span><span>x−0</span></span>≤1</span>
\frac{\sin(x)-\sin(0)}{x-0}\leq 1</span> so
<span>sin(x)≤<span>x</span></span>
